The Defence Research and Development Organisation (DRDO) releases the CEPTAM 11 Tier 2 provisional answer key for the Senior Technical Assistant-B (STA-B) and Technician recruitment posts on its official website, drdo.gov.in. The Tier 2 examination for CEPTAM 11 is held on June 15, 2026. After the key is published, candidates can review their responses and estimate possible scores ahead of the final results. DRDO also provides an online objection facility for candidates who identify errors in the provisional answer key. To challenge answers, candidates use the designated question-challenge portal mentioned on the website, log in with the required credentials, and submit objections with valid explanations and any supporting documents where applicable. Objections are accepted only within the deadline specified by DRDO; submissions after the closing date are not considered. Candidates are advised to download and keep a copy of the answer key and to monitor the DRDO website for updates regarding the final answer key and result timeline.
